implantIntroductionThe implant technology developed as the all-on-four concept is offered as an alternative to conventional implant applications. In the all-on-four technique, 4 implants are placed in the interforaminal region in the mandible and in the pre-maxillary region in total edentulism cases. This application is based on the placement of two of these implants to the anterior region so as to be perpendicular to the occlusal plane, and on the placement of two implants to the posterior region so as to be inclined 30-45o. These implants are ensured to function by making immediate fixed complete denture over them. The patient is administered with permanent fixed full arch restoration 3 months later. The reduction of surgical procedures and the functioning of immediate dentures are important by means of this system. The purpose of this study is to compile the clinical and research articles regarding the all-on-four implant concept, to determine the basic principles of this concept, and to present the advantages and disadvantages of the method. The all-on-four concept can be an alternative and potential treatment method especially in atrophic edentulous jaws, its routine clinical practices can be performed, but it is necessary to increase long-term clinical controlled studies.

Aesthetic restorative efforts in the formation of beautiful smiles are defined and guided by certain universal principles. An understanding
of the science of color and color perception is crucial to success in the ever expanding field of aesthetic restorative dentistry. Just as
the disharmony is created by a discordant note in a symphony, the wrong shades can destroy the result and thus, this necessitates the
thorough knowledge and understanding of the concept of shade selection.

The prevalence of teeth carriers of periodontitis apical is universally high. Only the decontamination of the root canal
system through cleaning, it’s shaping and its waterproof filling can ensure the eradication of infection at the level of the peri apex.
The purpose of this prospective study was to establish the semiological profile of different types of periodontitis apical. The different
characteristics used are subjective signs reported by the patient about the pain but also the clinical and radiographic features of each
tooth with apical periodontitis.

Cleft lip is a common craniofacial anomaly. Median cleft lip is a midline vertical cleft through the upper lip. Of all the types of clefts, minimal Median cleft of the upper lip is a very rare craniofacial anomaly.

Parry-Romberg syndrome is a rare disorder characterized by slowly progressive deterioration of the skin and soft tissues of half of the face. The syndrome presents with characteristic skeletal, dental, and soft tissue changes in the affected half of the face, with or without neurological signs and symptoms.

Periodontal disease is a major oral health problem, in which specific species of bacteria play an important role in its progressing and severity. Because chronic periodontitis is believed to be asymptomatic in its initial stages, it has been suggested that individuals may be unaware of their clinical periodontal status [1-3] and underestimate what treatments are required, as judged by dental professionals [4].

In this era of implant dentistry, the teaching and indications for removable prosthodontics is becoming a lost art, especially in affluent urban environments, where most replacements are accomplished by the use of implant fixtures. Removable prosthodontics is still being taught and is used in rural areas and in the elderly patients or medically compromised individual.

We set out to determine the possibility of radiographically evaluating the degree of marginal bone loss in humans after functional loading of implants at sites of guided bone regeneration (GBR) with autogenous tooth-based bone graft (ATBBG) material (AutoBT®, Korea Tooth Bank, Seoul, Korea).

Age estimation of unknown human cadavers is important in setting a crime investigation, such as homicide, suicide or in mass disaster
because it can guide forensic investigators to the correct identity among a large number of possible matches. More and more the
courts ask for medico-legal age estimations of unknown human cadavers by forensic dentistry.
